If eight avacados cost $2.64, how much would five avacados cost? Do this in algebra, including your word problem setup and through solution check.

The algebra is simple.
Or is it?

i'm having a hard time w/ our project in chemistry...plz..i need ur help..i need some ideas...
we are required to make a device out of indigenous materials..a device that can filter out a (detergent/bath)soap solution into clean water that can be used again...4 washing dishes,hands...
what are some of the uncommon but practical processes can i use?
-i've heard about reverse osmosis...but how can a freshman student lyk me do such stuffs...they say its hard..
here are also some of the things that i've researched:
-electrocoagulation - too complicated ..i think it uses electricity
-coagulation

x – 5 > 6 or 2 – x > 4
The compound inequality is equivalent to
x > 6- (-5) or 2-4 > x
which in turn is equivalent to
x > 11 or x < -2
solution: (-infinity,-2)U (11,infinity)

I have the solution on a graph line
but am not getting the solution checking besides the usual "plug in"

3/7x + 5/9y = 27

1/9x + 2/7y = 7
solve by any method:

27x+35y=(97)*27
27x+35y=63*27
27x+35y=1701
27x+35y-35y=1701-35y
27x=-35y+1701
27x/27=(-35y+1701)/27
x=63

27x+35y=2619
(27x+35y)+(-27x)=2619+(-27x)
27x+35y=97*27
y=27(-x+97)/35
y=0

solution check?
there are more than one?
